SPECIFICATION forming part of Letters Patent No. 502,701, dated August 8, 1893.

Application filed September 6, 1892. Serial Ilm-445,164. (No model.)-

To all whom it may concern:

Be it known that I, HARDY W. CAMPBELL, a citizen of the United States, residing at Aberdeen, in the county of Brown and State of South Dakota, have invented certain new and useful Improvements in Heaters; and Iy do hereby declare the following to be a full, clear, and exact description of the invention, suchv as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ofI reference marked thereon, which form a part of this specification. I

The herein described invention relates to certain improvements in devices-by Ywhich much of the heat which ordinarily passes into the chimney, is utilized to heat the same or an adjoining apartment to that in which the stove is located, and to further provide for a circulation of the air in the apartment to the end that a uniform heating of the same throughout may be accomplished.

The invention consists in certain novel features in the arrangement and construction of parts, all as hereinafter set forth and pointed out in the annexed claims.

In theaccompanying drawings, in which my invention is fully illustrated, Figure l is a View in side elevation of the device arranged to heat a room adjoining that in which thel stove is stationed, the smoke-pipe of the stove extending through the partition wall. Fig. 2 is a perspective view of the heating-drum or radiator, a portion thereof being shown as broken away to disclose the inner air-circulating pipe and the detlecting-wing provided thereon. Fig. 3 is aperspective view of the adjustable section of the drum having the smoke-pipe connected therewith. Fig. 4 is a top view of the same, and Fig.5 is aperspective view of one of the devices for making the jointed sections of the drum adjustable.

Referringto the drawings by letter A indicates the drum or radiator which rests on the ioor of the apartment and extends nearly to The drum A communicates with the stovepipe O at or near the base of the drum and with the chimney D by means of pipe E, which enters the drum near the top of the same.

Within the drum A is located a pipe F, ex-

tending the entire length of the drum and communicating with the air of the room through the top of said drum at F', which, with the exception of this openingrfor pipe F, is completely closed at the top. The function of pipe F is simply that of an air-circulating pipe which as the air within the same is heated, Vdraws the air from the bottom of the roomv through the air-inlets G atl thebase of the drum. `By the circulation of airthus effected within a short time all the air of the room will have passed through the circulating-pipe F and be heated, while a great deal of heating is accomplished by radiation from the exterior of the drum or radiator A.

The space between the inner or air-circulating pipe F and the drum A, is obstructed at certain points by means of circular partitions or wings I-l, which extend halt way around the inner pipe and project flush with the inner face of the drum, thus ettectually partitioning the space and causing the smoke and heated air to be directed to the open side to get above the partitions as they are met. These are arranged alternately on one side and then the other of the pipe and in their combinedaction cause the smoke to travel from one side to the other in ascending the drum to pipe E, thus retaining the heat ot' the same some little time within the drum by reason of its circuitous route and givingagreater amount of heat than would otherwise be obtained.v A vertical partition I is also provided on each side of pipe F and vpreferably joined to the wing H located just above the smoke pipe C, which causes the smoke to descend to near the base 'of the drum and to heat the same through its full length.

The drum Aas well as the innercirculating-pipe-F is required (by reason of the variation met with in the size of rooms and locations of chimney-openings) to be made adj ustable and thereby make it possible to adapt IOO constructed as shown in Figs. 2, 3, and 4, the sheet metal forming the pipe or drum being lapped and provided on each lap With a casting M, shown in Fig. 5, which casting is irinly secured one on each side and connect-cd one with the other by means of bolts n which permit the laps to be drawn together and the size of the pipe or drum section adjusted as desired. The top of each section referred to is firmly riveted as shown at O.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as vfollows:

1. The means for heating adjoining rooms which consists in a stove arranged in one of said rooms in connection With the smoke pipe of said stove, leading through the wall separating the rooms a long vertical drum arranged in the second room, and extending from the Iloor to a point near the ceiling of said room, the smoke pipe ot said stove leading into said drum a iiue or chimney a connection with the upper end of said drum, a vert-ical open duct F, arranged within said drum and adapted to take the air from the floor line and a serios of segmental, inclined wings arranged between said duct F, and the Wall of the drum, substantially as described.

2. The combination in a heating device, of the long` drum and air duct F, arranged therein, a smoke pipe leading into opposite ends of said drum, the inclined Wings H secured upon said duct and extending between the saine and the inner Walls of said drums, the lower Wing H provided with downwardly projecting partitions I, said drum formed of single sheets of metal, having their edges brought together and held by the angle castings M and short bolts n, substantially as described. A

In testimony whereof I afiix mysignature in presence of two Witnesses.
